The Hayward Sense and Dispense sensing kit continuously tests the water's ORP (sanitation) and pH levels and reports the readings to your Hayward control, which then generates the correct amount of chlorine and dispenses the proper amount of pH reducer on its own. Instead of testing and dosing by hand, the water is sampled and adjusted continuously, so sanitizer and pH hold in range day after day with far less chemical handling.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e🚩 PRO TIP:\u003c\/strong\u003e Keep the probe tips damp at all times and never expose them to freezing temperatures — the HL-CHEM probes store wet in their caps, are hand-tightened only, and the flow cell must not be allowed to fully drain or dry out while the probes are installed.\u003c\/p\u003e\n\u003ch3\u003ePRODUCT FEATURES \u0026amp; SPECIFICATIONS:\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eBrand: Hayward\u003c\/li\u003e\n  \u003cli\u003eMPN: HL-CHEM\u003c\/li\u003e\n  \u003cli\u003eUPC: 610377235457\u003c\/li\u003e\n  \u003cli\u003eType: Pool Controls \u0026amp; Automation\u003c\/li\u003e\n  \u003cli\u003eFunction: Continuous ORP and pH sensing for automated chemistry control\u003c\/li\u003e\n  \u003cli\u003eSensors: Professional-grade ORP probe and pH probe included\u003c\/li\u003e\n  \u003cli\u003eORP Setpoint: 650 mV default, adjustable 400 to 900 mV in 5 mV increments\u003c\/li\u003e\n  \u003cli\u003epH Dispensing: 120 VAC and 240 VAC pigtails included for a pH reducing device (peristaltic pump or solenoid valve, sold separately)\u003c\/li\u003e\n  \u003cli\u003eCO2 Option: AQL-CHEM2 and AQL-CHEM2-240 CO2 pH reduction kits plug into the pigtail\u003c\/li\u003e\n  \u003cli\u003eCompatibility: Hayward OmniLogic, OmniPL and OmniHub controls; also ProLogic and AquaRite Pro\u003c\/li\u003e\n  \u003cli\u003eOmniPL Installations: Require the GLX-FLO flow switch (sold separately)\u003c\/li\u003e\n  \u003cli\u003eCross-Reference: AQL-CHEM (former part number designation)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFREQUENTLY ASKED QUESTIONS:\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWill the Hayward HL-CHEM work with my OmniPL?\u003c\/strong\u003e Yes — the Hayward HL-CHEM is the ORP and pH sensing kit for OmniPL, OmniLogic and OmniHub controls. An OmniPL installation also uses the GLX-FLO flow switch, and the HL-CHEM designation is the version to order for Omni systems.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIs the HL-CHEM the same kit as the AQL-CHEM?\u003c\/strong\u003e The Hayward HL-CHEM is the current part number designation for the Sense and Dispense sensing kit formerly designated AQL-CHEM, and it is the version built for Omni controls. An older AQL-CHEM unit from a ProLogic system is not compatible with OmniPL.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDoes the HL-CHEM dispense chemicals by itself?\u003c\/strong\u003e The Hayward HL-CHEM senses ORP and pH continuously. The control generates chlorine based on the ORP reading and signals a pH reducing device — a peristaltic pump or solenoid valve, sold separately — through the included 120 VAC or 240 VAC pigtails. The AQL-CHEM2 CO2 kit also plugs into the pigtail for CO2-based pH reduction.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWhat do the HL-CHEM probes need to stay accurate?\u003c\/strong\u003e Keep the Hayward HL-CHEM probe tips damp at all times, even in storage, hand-tighten the probes only with no tools, and protect them from freezing temperatures. The flow cell must not fully drain or dry out while the probes are installed.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWHY SHOP WITH AL'S COOL POOL STORE?:\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e✅ Fast, reliable shipping on every order\u003c\/li\u003e\n  \u003cli\u003e✅ Genuine OEM and top-brand parts only\u003c\/li\u003e\n  \u003cli\u003e✅ Knowledgeable pool \u0026amp; spa experts ready to help\u003c\/li\u003e\n  \u003cli\u003e✅ Hassle-free returns and satisfaction guarantee\u003c\/li\u003e\n  \u003cli\u003e✅ Authorized Dealer — shop with confidence\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":46482175754375,"sku":"HL-CHEM","price":1178.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0634\/1217\/4983\/files\/hayward-sense-and-dispense-hl-chem-complete-kit.jpg?v=1794318197","url":"https:\/\/alscoolpoolstore.com\/products\/hayward-sense-and-dispense-hlchem","provider":"Al's Cool Pool Store","version":"1.0","type":"link"}
